Subject: [PATCH 3/5] ARM: OMAP1: Fix dpll1 reprogramming not actually allowed
DPLL1 reprogramming to a different rate is actually blocked inside
omap1_select_table_rate(), resulting in the defalut rate of 60 MHz
always used instead of the one selected in .config. Fix it.
Created against linux-3.2-rc2, tested on Amstrad Delta on top of
linux-omap/fixes.
